A little time consuming but well worth the effort since they aren't that difficult.
1/4 cup soymilk
egg replacer to the equivalent of 1 egg (I use Orgran No Egg)
Make the egg replacer as per packet directions.
Mix the egg replacer in a bowl with the soymilk.
In a separate bowl mix together
1/2 cup wholemeal bread crumbs
1 teaspoon paprika
1 teaspoon ground sage
2 tablespoons nutritional yeast
I use the small size container of mushrooms. This makes just enough coating for them all. I think its 200g!
Pick a mushroom up using a fork & dip it first in the eggwash mixture & then in the crumbs. I find it just works easiest with a fork. I actually use 2 forks so I can then help the mushroom slide off the other fork and onto the baking tray.
Delicious by themselves or as part of a salad.
